Comparison of two U.S. Environmental Protection Agency species sensitivity distribution methods for calculating ecological risk criteria
|
ABSTRACT
Two major methods used by the U. S. Environmental Protection Agency (USEPA) to calculate ecological risk criteria using "species sensitivity distributions" (SSD) are compared using identical datasets. One method is the current USEPA Office of Water method for deriving acute numeric water duality criteria (EPA-FAV method). The 95% protection level generated by this method is the Final Acute Value (FAV). The other method is the USEPA Office of Pesticide Programs log normal dist...

Ecological Risk Assessment of Regions Along the Roadside of the Qinghai-Tibet Highway and Railway Based on an Artificial Neural Network
Human and Ecological Risk Assessment
; ABSTRACT A concept model of regional risk was constructed for the characteristics of ecosystems alongside the Qinghai-Tibet highway and railway based on the MLP (Multilayer perceptron) model. Seven indices such as snow hazard, drought hazard, and landslide were selected in order to evaluate the

Performing Spatially and Temporally Explicit Ecological Exposure Assessments Involving Multiple Stressors
Human and Ecological Risk Assessment
; ABSTRACT Ecological risk assessments have traditionally focused on estimating risk associated with a receptor's exposure to chemical stressors in abiotic (soil, water, etc.) and biotic (tissues, prey items) media. However, a free-living receptor is also constantly challenged to avoid or minimize
